Tof/,ZZ whom it may concern:

Be it known that I, ARTHUR J. ADAMS, a citizen of the United States, residinat Chicago, in the county of Cook and tate` of Illinois, have invented a new and useful Folding Carriage, of which the. following is a specication. A

My invention relatesv articularly to folding baby carriages,^dol carriages, go-carts and the like; and my primary object is to provide .improved means for locking the -wheel supports in an u right osition.

The invention may e emp ovled to peculiaradvantage in connection wit folding carriages of the type disclosed in my Patent No.. 789,810, granted May 9, 1905.

, The invention is illustrated in the accompanying drawings, in which Flgure 1 represents la side elevational view lof a folding carriage constructed in accordance with my present improvements; Fig. 2,

. a broken perspective detail view of one of the connections between aair of wheel supports Fig. 3, a similar view i lustrating a modification of said connection; Fig. 4, an enlarged section taken as indicated at line 4 of Fig. 6

.and showing a locking device employed in connection with a pair of folding links formlng a connection between apalr of wheel supports; Fig. 5, a section taken as indicated kat line 5 of Fig. .4; Fig. 6, a plan section taken connecting the wheel supports and serving to secure the same in an upright position; B, a

, foldable, seat-supporting frame, from winch is,suspendedv a seat, B1 C, ahandle pivotally `"coiilefcted withA the rear end of the running gear frame andfadaptedto swing forwardly and downwardly yupon therunning gear frame in a manner now well understood; andA D, a foot sup ort of the `construction shown and claime in my application No. 329,336 led August 6th, 1906.

The frame,rA, may be of any suitable construction. It comprises, as shown, sideV members, (L, and cross members, (L1. The side members are equipped with clips or stamp-. ings, (L2, with which the u per ends of the wheel supports are joined y longitudinally extending pivots, (L3, in' a manner now well understood.

The two wheel supports at each side ofthe frame are joined in a pair by longitudinallyextending bars, (L4, which connect the lower' ends of said supports, so that each side pair of wheels will swing as a unit. The lower ends of thewheel supports lhave connected therewith the out-turned spindles, (L5, upon.

which are journaled the wheels, (L6.

- The link mechanism A2, comprises in preferred form a folding front cross-member, a7,

a folding rear cross member, (LB, and a longitudinal-connecting link, (L11. Each folding cross bar comprises a pair of links, (L10, (L11,

which are joined together at the median longitudinal plane of the running gear frame by a vertical pivot, (L12, short, twisted links, (L13, joined to the outer entremities of the links (L10, (L11, by vertical pivots, (L14; and angleform clips, (L15, having transversely-extending arms, (1,111, joined by horizontal, longitudinallydisposed pivots, (L17, to the outer ends of the links, (L13, and having longitudinally-disposed arms, (L18, securely fastened by means of rivets, (L19, to the wheel supports, A1, some distance above the lower ends thereof. The links, (L10, (L11, preferably comprise-.flat bars which are disposed in a horizontal plane when the wheel supports are in the upright position; and the short links, (L13, preferably comprise iiatbars which are given a quarter rtwist `to adapt their ends to conform to the members with which they are connected. The link, (L1, preferably comprises a flat bar Whose ends are pivotally connected with e pivots, (L11, so thatv the link, a, occupiL L median longitudinal plane, as will be clear.

understood from Fig. 6.l For the purpose "of securing the links in the position shown lnFig. 6 and locking the wheel supports in an upright position, I equip one of the links, preferably theV front link, (L10, with ahousing or clip, (L20, in which works a -U-shaped lockslide, (L21, against which presses a spring, a, coniined between the slide and the opposite end of the loop or cli (L20.

The slide, (L11, has down-turned endanges, (L23, which,

'l .automatically retracted and will then 'auto-y member,

embrace the edges of the bar, al", andare adapted to engage they projecting end, a, of the corres onding bar, alf. This lwill be clearly un erstood from Fig. 4. Said `projecting end, azis beveled or rounded, as in-- dicated at c', so that when the links are swung from the.. position shown' in Fig. 7 to the position show nA in Fig. 6 by the operation of swlnging the'wheels to thelr vertical posltion, lthe locking member or slide, (L21, will be matically return under the force of its spring toefl'ect locking connection. v z From theforegoing-detailed description,

the operation of 'the' wheel-support-securing fmechanis'm will bereadily understood.

When it is desiredlt'o fold the wheels laterally inwardly from the position shown in Fig. 6 to the position shown in Fig. 7 .this may be accom lished by releasing the locking om engagement with the ex- 1 ten-sion, a2, of the front link,a'11, whereupon one lateral pair of wheels may be swung inwardly and' upwardly and the other lateralv 25 P air of vWheels may then be swung inwardly and upwardly to occupy the position shown in Fig. 10.

From the position of the cross bars, a1, of

' the runninggear frame with relation to the wheel supports, A1, as` the same appears from Fig. 1, it willbe understood that ythe -wheel supports may be'folded to Lthe position indicated .in Fig. 10 without interference with the cross bars.

In the initial ortion of the folding operation, the cross ars, a7, a?, are flexed upon the pivots, a, in whichv operation the links,

ka.1",a., swingv forwardly by a species of parallel motion, about the' vertical pivots, a. One lateral pair of wheels .1s swung upwardly,

. while theother vpair remains, for the time being, stationary. The horizontal, longitudi dinal pivots, a, permit this action as will be understoodfrom Fig. 9.

'In the modification shown in Fig. 3, Ihave substituted a hinge, y",for the twisted link, a, and the clip, a". The hinge has a pintle,

1, which isdisposed in a horizontal longitu.

dinal direction. Oneleaf of the hinge is connected by a vertical ivot, f 2, to the adjacent link, aiand the ot ier leaf has its free ex- "tremity bent at right angles to the body of i the leafy and secured by a rivet, f3, to the wheel su port, 'Ah Thus, thehinge, secured as state affords-.a doublepivotal or universal'connectionbetween the link, al", and the wheelisul port, A1.-

The oregoingdetailed description has been given for clearness of understanding lonly-and no undue limitation is to be understoodl therefrom.
